SECTION 11-BATTERIES CAUTION New batteries MUST be fully charged prior to initial use of the wheelchair. ALWAYS charge new batteries before initial use or battery life will be reduced. As a general rule, you should recharge your batteries as frequently as possible to assure the longest possible life and to minimize required charging time. Plan to recharge them when you do not anticipate using the wheelchair. Basic concepts which will help you understand this automatic process are: The amount of electrical current drawn within a given time to charge a battery is called "charge rate". If, due to usage, the charge stored in the battery is low, the charge rate is high. As a charge builds up, the charge rate is reduced, and the battery charger rate decreases to a "trickle charge". NOTE: If the batteries need to be charged more often or take longer to charge than normal, they may need to be replaced. Contact a qualified technician. NOTE: The batteries can be charged using the on‐board battery charger or by plugging an independent battery charger into the port located on the front of the joystick. Battery Charger Operation ƽ WARNING Read and carefully follow the manufacturer's instructions for each charger (supplied or purchased). If charging instructions are not supplied, consult a qualified technician for proper procedures. NEVER leave the charger unattended when the charger circuit breaker is tripping. Ꮨ DANGER Use of improper extension cord could result in risk of fire and electric shock. Part No 1125085 67 Pronto® M51™and M61™with SureStep®
